Frequently asked questions: wheels for the BMW 1 Series M135i (F20/F21)

What are the original wheel offsets for a BMW M135i F20 or F21?

A staggered fitment, according to its Swiss vehicle type records: 7.5J with an offset of 45 at the front and 8J with an offset of 52 at the rear, in both 18 and 19 inches. [4, 27]

Which tyres, and which load index, for a BMW M135i F20 or F21?

In 19 inches, 225/35 R19 with a load index of 88 at the front, i.e. 560 kg per tyre, and 245/30 R19 with an index of 89 at the rear, i.e. 580 kg; in 18 inches, 225/40 R18 with an index of 88 at the front and 245/35 R18 at the rear. [4, 27, 28, 29]

What load per wheel for a BMW M135i F20 or F21?

The highest permissible load in its Swiss vehicle type records is 1,010 kg on the front axle and 1,120 kg on the rear axle, i.e. 505 and 560 kg per wheel. The 245/30 R19 rear tyre with a load index of 89 carries 580 kg. [27, 28, 29]

Which PCD, centre bore and bolts for a BMW M135i F20 or F21?

The PCD is 5x120, the centre bore 72.6 mm, and the wheels are held by M14 x 1.25 wheel bolts, according to koleso.ee and SCC. The tightening torque is not published: the sources read do not agree. [1, 2, 3]

Same fixing measurements

As original equipment, these cars have the same PCD, centre bore, thread and fixing as the BMW 1 Series M135i (F20/F21): PCD 5x120, centre bore 72.6 mm, thread M14 x 1.25, fixing: wheel bolts.

Same fixing measurements; original diameters and offsets: see each car's page. Bolt seat, width and brake clearance: our design office checks them for your car before machining.

Custom forged wheels for the BMW 1 Series M135i (F20/F21)

  • Forged 6061-T6 aluminium
  • 5-axis CNC machining
  • Designed to JWL/VIA standards
  • Fitment worked out for your BMW 1 Series M135i (F20/F21)

BMW M135i F20/F21: 5x120, a 72.6 mm hub, M14 x 1.25 bolts

The BMW M135i of the second-generation 1 Series, five-door (F20) or three-door (F21), rear-wheel drive or xDrive, with 235 kW then 240 kW, whose first Swiss vehicle type record dates from June 2012, is 5x120 on a 72.6 mm hub, with M14 x 1.25 wheel bolts: koleso.ee and SCC give these measurements, each cited in the table. The two sources do not give the same tightening torque: we do not publish it. The 1 Series F40 that succeeds it changes PCD and has its own page.

18 and 19 inches, a staggered fitment

The vehicle type record of the Swiss Federal Roads Office (ASTRA), the document that sets the tyre and wheel combinations a car may carry, permits a rear wheel wider than the front for the M135i: 7.5J with an offset of 45 at the front and 8J with an offset of 52 at the rear, in 18 inches with 225/40 R18 and 245/35 R18 tyres, in 19 inches with 225/35 R19 and 245/30 R19 tyres.

The load the wheel must carry

It is rear-wheel drive, with more load at the rear: the highest permissible load in its records is 1,010 kg on the front axle and 1,120 kg on the rear axle, i.e. 505 and 560 kg per wheel. The tyre keeps at least the load index of the original fitment, 88 at the front and 89 at the rear in 19 inches (reading a tyre). Braking sets the smallest possible wheel diameter: the guide wheels and brakes explains why.

What these measurements say about a forged wheel

The offset positions the wheel in the wheel arch: a wider wheel, or a lower offset, brings it closer to the wing. The design office starts from the measurements on this page, your brakes and your tyres to calculate the width and offset of your wheels, then submits them to you. The offset calculator compares two fitments: it compares, it does not choose the measurement for you.

Roadworthiness test: what is examined

The French roadworthiness test (contrôle technique) examines the wheel without removing it (cracks, deformation, a wheel that protrudes beyond the bodywork) and verifies that the tyre size is one provided for by the manufacturer or accepted as equivalent. Keeping a tyre size from the original fitment, and at least its load index, avoids having to justify it; the details are on the roadworthiness test and registration page.

What we record before machining

Configure your forged wheels for the BMW M135i (F20/F21)

Our design office establishes your car's measurements from its exact version, stated on the registration certificate, and presents them to you before machining. Each set is cut from forged 6061-T6 aluminium, machined on a 5-axis CNC centre, in monoblock, two-piece or three-piece construction; our wheels are designed to JWL/VIA standards. Prices by diameter and the lead time are given on this page, under “What Onyx can make”. Start your configuration or write to contact@onyxforgedwheels.com.
